I know this is for Sara, but you could get modeling clay and make a model of the spike. After that you could cast it with almost anything (smooth cast, resin, ultra cal, hot glue, maybe even silicone caulking etc. . . ) and then pour the bondo or a rondo mix into the mold you made of it. Doing that would ensure that all of the spikes are identical. I've made similar molds out of hot glue and just straight fiberglass resin. You just have to use vaseline or some other type of release agent so your casting agent won't stick in the mold.
Hope this helps.
and once again. an idea I've never thought of.
